Single channel potentiostat

20A Potentiostat with Current Booster(CS2020B)

CS2020B can boost the current upto ±20A. It can be connected with single channel models such as CS350M, CS310M.

CS350M can be used alone as ordinary single channel potentiostat(±2A), and can also be used with CS2020B booster(±20A).
